I've wound a bunch of them on drill bits.
The last time I did this, I was building a little transmitter for
foxhunting. I had plenty of enamel wire on hand, and saw no reason not to
literally roll my own.
There used to be a bunch of stuff over at the ARRL website on the subject.
I think the math (diameter, etc.) is in the Antenna Book.
